Mark Zielinski knew he was onto something when his mice stopped sleeping. Normally, the animals woke and slept on a 12-hour cycle. When the lights were on in the lab, the mice were active. When it went dark on a timer, down they went. But Zielinski, who teaches psychiatry at Harvard Medical School, had recently […]

Food and health cliches revisited – Wake Forest

An apple a day keeps the doctor away – I always liked that one. While apples boast many health benefits, they do not, sadly, bulletproof us against all diseases.

“Everything our parents said was good is bad,” complains Alvy Singer, the character played by Woody Allen in “Annie Hall,” his 1977 Oscar-winning romantic comedy.

Green-vegetables

That’s a bit of an exaggeration, but when it comes to what certain foods can do to or for you, it’s probably best to take motherly advice, familiar sayings and other bits of conventional wisdom with a grain of salt.

“There’s some validity to some of them, but many of them are just old wives’ tales or myths that have trickled down over the years,” said Annette Frain, a registered dietitian at Wake Forest Baptist Medical Center in Winston-Salem, North Carolina. Continue reading

Tricking Your Brain Into Helping You Lose Weight

If, like many folks, you overindulged during the recent holidays, perhaps this item I wrote back when the blog was still in diapers might be of help.

Besides, I think the brain is amazing and we can’t know too much about it.

One Regular Guy Writing about Food, Exercise and Living Past 100

Regular readers know that I am retired and have been taking courses from The Great Courses for some time. Lately, I have become fascinated with the brain and how it functions.

The latest class I am studying is “The Neuroscience of Everyday Life” taught by Sam Wang, Ph.D, Associate Professor of Molecular Biology and Neuroscience at Princeton University. Additionally, Professor Wang is the co-author of the best-selling book Welcome to Your Brain which has been translated into 20 languages.

Here is the best-selling book Professor Wang co-wrote

I have only just begun reading the book, but I ran across a passage on page 36 that I thought would interest and benefit readers of the blog. The following is from a two-page write-up titled Tricking Your Brain Into Helping You Lose Weight.

This is the conclusion of those two pages:

How to Use Your Brain for Weight Control

I took a course in The brain six years ago and was so inspired by what I learned that I posted on it. Thought you newer readers might get something out of it.

Tony

One Regular Guy Writing about Food, Exercise and Living Past 100

Exercise and intelligent eating are the keys to weight control and healthy living. Everyone knows that 30 minutes on the treadmill burns X amount of calories depending on your weight. The role of exercise in healthy living and weight control is straight forward and doesn’t need explaining. The exercise of the brain in weight control is another matter.

In order to understand it, you need to know a few basic facts about parts of your brain and how they function. If you are willing to wade through a couple of basic biology facts, I think you will emerge at the other end with a new tool in the universal ongoing battle of the bulge.

For this subject we need to focus on just two parts of the brain and how they work, together and separately.

The first is the amygdala. This is the part of the brain that is central…

Tips on sharpening your brain – WebMD

I write about exercise almost daily and about the brain nearly as often, but I think they really need to be tied together for the best understanding. Also, because we all want to live past 100, we certainly want the old cabeza to fully functional.

WebMD has a nice 12 part slide show  called Tips to stay smart, sharp and focused. If you want to experience the entire show, just click the link above. I am have picked out a few examples for the folks too lazy busy to do the whole thing right now.

Number one is superb: USE YOUR BRAIN  “It’s true: Use it or lose it. Stretching your brain keeps your mind sharp. People who are more active in mentally challenging activities are more likely to stay sharp. Try these:
•    Read a book.
•    Go to a lecture.
•    Listen to the radio.
•    Play a game.
•    Visit a museum.
•    Learn a second language.”

Bad habits that can hurt your brain – WebMD

I  write often about the benefits the brain gets from exercise and how we should make regular exercise a priority as much for our mental health as physical. That is a good positive target.

It turns out that WebMD also has some excellent suggestions for keeping our brains clicking on all cylinders, but they approach from the negative side. Not doing harmful things is also an important consideration in getting to old age with a fully functional brain.

Here is their list of bad habits:

Missing out on sleep. WebMD notes, “… lack of sleep may be a cause of dementia, including Alzheimer’s disease. It’s best to have regular sleeping hours. If you have trouble with sleep, avoid alcohol, caffeine, and electronics in the evening, and start a soothing bedtime ritual.”

11 Ways Men And Women Think Differently

I will be 77 years old next month. Have had two marriages each of which lasted 11-1/2 years. I have fathered two daughters. My current relationship is in its fourth year and I am still not sure I have a clue about women. I learned a lot from this post. Hope you will, too.

Our Better Health

Men and women are different. There are some good biological reasons for that. Studies of brain scans of men and women show that women tend to use both sides of their brain because they have a larger corpus callosum. This is the bridge between the two hemispheres of the brain and allows women to share information between those two halves of the brain faster than men. Men tend to use the left side of the brain which is the more logical and rational side of the brain. Scans also reveal other interesting ways in which men and women do things differently or process information differently from each other.

HERE ARE 11 WAYS MEN AND WOMEN THINK DIFFERENTLY:

1. PERCEPTION
Women have smaller brains that are more tightly packed with connections. This allows them to perform better at tasks involving the bigger picture and situational thinking. A man’s brain tends to…

Aerobic Exercise Preserves Brain Volume / Improves Cognition – RSNA

I seem to remember a line from a Clint Eastwood movie – Go ahead, make my day.  That’s how I feel every time I read something in the press about how exercise helps the brain the function better. It absolutely makes my day.

This is from the Radiological Society of North America (RSNA):

•    Aerobic exercise may increase brain volume and cognitive function in people with mild cognitive impairment.
•    MRI results showed increased local gray matter volume in patients who engaged in either aerobic or stretching exercises for six months, but some white matter atrophy in the stretching group.
•    Cognitive testing revealed the aerobic exercise group also showed improvement in executive function after six months.

brainexercise.jpg

Using a new MRI technique, researchers found that adults with mild cognitive impairment (MCI) who exercised four times a week over a six-month period experienced an increase in brain volume in specific, or local, areas of the brain, but adults who participated in aerobic exercise experienced greater gains than those who just stretched. The study was presented at the annual meeting of the Radiological Society of North America (RSNA). Continue reading

Portions of the Brain Fall Asleep While we are Awake …

I am blown away by the brain and how it functions in our body and allows us to function. Remember, the brain which accounts for about two percent of our body weight burns around 25 percent of the calories we use in a day. This item from Neuroscience News moves the needle further.

When we are in a deep slumber our brain’s activity ebbs and flows in big, obvious waves, like watching a tide of human bodies rise up and sit down around a sports stadium. It’s hard to miss. Now, Stanford researchers have found, those same cycles exist in wake as in sleep, but with only small sections sitting and standing in unison rather than the entire stadium. It’s as if tiny portions of the brain are independently falling asleep and waking back up all the time.

brain-sleep-wake-neurosciencenews-public.jpg

What’s more, it appears that when the neurons have cycled into the more active, or “on,” state they are better at responding to the world. The neurons also spend more time in the on state when paying attention to a task. This finding suggests processes that regulate brain activity in sleep might also play a role in attention.

“Selective attention is similar to making small parts of your brain a little bit more awake,” said Tatiana Engel, a postdoctoral fellow and co-lead author on the research, which published Dec. 1 in Science. Former graduate student Nicholas Steinmetz was the other co-lead author, who carried out the neurophysiology experiments in the lab of Tirin Moore, a professor of neurobiology and one of the senior authors.

Women multitask better than men – Study

This study from the Higher School of Economics Neurolinguistics Laboratory in Russia puts forward some fascinating observations on the differences between men’s and women’s brains. Ironically, these latest findings seem to support some vintage gender stereotypes.

It has long been known to science that women find it easier than men to multitask and switch between tasks. But identifying exactly which areas of male and female brains respond differently and why has so far been unclear. According to researchers from the HSE Neurolinguistics Laboratory, men need to mobilize additional areas of their brain and use more energy than women when multitasking.

Why Men Find Switching Tasks More Difficult
Needing to switch attention between tasks causes stronger activation in certain brain regions in men compared to women.Exactly why their brains function differently in such situations has so far been unclear. Recent research reveals that male brains appear to consume more energy when they need to shift attention. In addition to this, in men there is greater activity in the dorsolateral prefrontal areas of the brain compared to women, as well as activation in some other areas which is not usually observed in women.

World chess champion on exercise – WSJ

I have written it previously and I will repeat it: I love it when the news meets my bias. This week Jen Murphy wrote in the Wall Street Journal about three time world chess champion Magnus Carlsen and his training. Think about it, nothing is less physical and more cerebral than a game of chess, right? Yet, Mr. Carlsen says, “… he believes a healthy diet and physical training are crucial for a chess master to remain at peak, just as they are for other types of athletes. “I get bored very easily, so I don’t do well in the gym,” Mr. Carlsen says. “Luckily for me, I have a real love of sport.”

Isn’t that wonderful?! He considers a healthy diet and physical training to be ‘crucial’ for success in chess.

Magnus_Carlsen_Tata_Steel_2013.jpg

World Chess Champion Magnus Carlsen became a Grand master at the age of 13, one of the youngest in history.

How does he work out? “When Mr. Carlsen is on the road for a tournament, he depends on his workouts to help him relieve tension and relax. He might run intervals on the treadmill at a hotel gym, adjusting the incline and intensity for 30 to 60 minutes. “Running is a time where I can go through game strategies,” he says.
After he gets his heart rate up, he winds down with a series of stretches, or he will flow through yoga sequences for 20 minutes. “Much of my core work comes from yoga,” he says. “I’m not the type to go to the gym and run through reps and sets of exercise. I need something more fluid and fun.” If he can find a hot yoga studio, he’ll attend a class.”

I love that a chess grand master includes healthy food and good exercise in his training regimen. Keep in mind that he is just practicing what I have been preaching here for some years. Although the rest of us aren’t grand masters and maybe don’t even play chess, the same principles apply. Eat intelligently and exercise regularly to succeed in living a healthy life.

9 Reasons To Eat Honey Daily

I was lucky enough to be exposed to some of these facts about honey years ago. Been using it ever since.

Honey

Tony

Our Better Health

 The possible health benefits of honey have been documented in early Greek, Roman, Vedic, and Islamic texts and healing qualities of honey were referred to by philosophers and scientists all the way back to ancient times, such as Aristotle (384-322 BC) and Aristoxenus (320 BC). – Joseph Nordqvist, Medical News Daily
For something that tastes so good, honey isn’t consumed all that often. Besides being delicious, honey is also densely packed with valuable nutrition, such as nutrients. Honey is also quite healthy: a tablespoon of raw, unadulterated honey contains 64 calories, and is free from cholesterol, fat, and sodium.
The ideal nutritional composition of honey almost assuredly helps give the natural sweeter its health-promoting properties. Here, we’re going to discuss nine such health benefits of this sweet nectar.

Research Reveals How A Single Choice Affects Mental Health More Than Medications

Regular readers know that I have stressed the importance of exercise for the brain. So, it seems a logical corollary that food also affects the brain as well as the body.

nutrition

Tony

Our Better Health

“We need to get serious
about the critical role played by nutrition.”

– Julia Rucklidge, Clinical Psychologist

We pretty much all agree that good nutritional habits are vital to good physical health, yes? But what about mental health? Do good nutritional habits translate to a healthier mental state? On the surface, it would make sense. After all, the food that we eat contains nutrients – and these nutrients are transported throughout our entire body via our bloodstream. We already know that the brain requires nutrients to operate effectively…so, yeah, it makes sense.

But is eating right more important to mental health than prescription medicine?

Ah, this is a bit trickier. After all, pharmaceuticals are research-intensive and science-based products that have undergone extensive trial and error, often over a period of multiple years. These same products have earned the coveted “seal of approval” from the Food and Drug Administration (FDA)…no easy…
